about the project

The aim of this project is the development of Linux device drivers and user
space programs for the Siemens Gigaset 307x/SX2x5
family of ISDN DECT bases.

The drivers connect
the base to the Linux system, either through a direct
USB connection or through one of the DECT data devices M101 (serial) or
M105 (USB).
They provide integration with Linux ISDN subsystems CAPI and/or ISDN4Linux for making ISDN
connections through the base, as well as character devices for direct access
to its AT command interface.

current status (2014-09-28)

All drivers are part of the standard kernel.
They support data (HDLC) and voice
connections, outgoing and incoming, through
direct USB connection to the base as well
as cordless DECT devices
M101 (RS232) or M105 (USB).

CAPI is the recommended ISDN subsystem
since kernel release 2.6.34.2.
It supports popular CAPI 2.0 applications such as pppd
with
capiplugin,
Asterisk with
chan_capi,
capifax
or jAnrufmonitor.
Support for ISDN4Linux applications is
maintained via the compatibility module
capidrv.ko.
For details, see the
drivers page.

For support in kernel releases before 2.6.34.2, see the
old kernels page.

supported devices

The following table lists the devices known to work with this release.

There is also limited support (unimodem mode only)
for using the DECT data devices with the following ISDN DECT bases:

The Gigaset M34 / Sinus 702 data USB adapter does not work with these drivers.
Its USB interface is completely different from that of the M105.
Gigaset won't provide any information about it.
As a consequence we are unable to add support for that device.

We lack information about other models (in particular, the newer
CX 34x / SX 44x / Sinus 722 series bases)
so we cannot say whether they will work with our drivers.
If you own such a beast you are welcome to try them and report the results.

getting started

For information on how to get your Gigaset
device recognized by your Linux system, read
the drivers page or,
if your system uses an older kernel release
than 2.6.34, the
old kernels
page.

If you are interested in doing more with your
Gigaset than just using it as an ISDN card for
your Linux PC, have a look at the
front-end programs
page afterwards.
